Applications: Underground coal mine transportation, dry material handling.
Steel Cord Flame-Retardant Belts
Structure: High-tensile steel cord core with flame-retardant rubber covers.
Features: Ultra-high tensile strength, low elongation, impact resistance, and long-distance conveying capability (up to 10 km).
Standards: Complies with MT914, ISO 340, and DIN flame-retardant requirements.
Specifications: Tensile strength grades: ST1000–ST5400. Widths: 800–2400 mm.
Applications: Heavy-duty long-distance conveying in coal mines, ports, and metallurgical plants.
Anti-static Flame Retardant Conveyor Belt
This kind of belt is a high-performance special conveyor belt specially developed for flammable, explosive and static-sensitive working environments, integrating dual core functions of anti-static and flame retardant. It is widely used in underground mining, chemical industry, coking and other fields where safety requirements are extremely high, providing a reliable and safe conveying solution for material transportation in harsh conditions.

Flame retardant: Self-extinguishing
Anti-static: Yes
Tensile strength: 400–2000 N/mm
Width: 500–2000 mm
Operating temperature: -20°C to +80°C
Application: Coal mine, underground, flammable & explosive working conditions
Core Performance & Advantages
Excellent Flame Retardancy
Comply with MT914-2008 (China Mine Safety Standard) and relevant international standards. It has the characteristics of non-combustible, self-extinguishing quickly (self-extinguishing time ≤ 3s) when leaving the fire source, no open flame spread, low smoke and low toxicity, which can effectively control the fire range and reduce fire losses.
Effective Anti-static Performance
The surface resistance is controlled within 1×10⁸ Ω, which can quickly release the static electricity generated during the operation of the conveyor belt, avoid static sparks, and prevent explosions caused by static ignition of flammable gases or dust.
High Strength & Wear Resistance
The belt body is made of high-strength canvas or whole core base material, combined with high-quality rubber or plastic covering layer, which has strong tensile strength, impact resistance and wear resistance. It can adapt to the harsh working conditions of heavy load, long distance and frequent start-stop, and the service life is 1.5-2 times that of ordinary conveyor belts.
Stable Operation & Easy Maintenance
The belt body is flat and smooth, with good flexibility, not easy to delaminate, crack or deform. It runs stably during operation, with low noise and low maintenance cost. Daily maintenance only needs simple cleaning and inspection, which saves time and labor.
